Description

Non-immediate planting body for old people

Technical Field

The application relates to the technical field of dental implantation, in particular to a non-immediate implant for the elderly.

Background

Dental implant restoration has become the preferred restoration method for patients with dental loss, and a great number of elderly patients without dental jaws increasingly require dental implant restoration. However, the long tooth missing time of the elderly patients, physiological alveolar bone absorption after tooth missing, maxillary sinus gasification or insufficient alveolar bone amount caused by various diseases bring challenges to dental implantation repair. In addition, the bone marrow tissue has the characteristics of weakened tissue regeneration capability, increased risk of systemic diseases, reduced expected bone proliferation effect, poor operation tolerance and the like. The planting of the old can be divided into immediate load planting and non-immediate load planting clinically. Since the condition of insufficient bone mass generally exists in the aged tooth loss patients, non-immediate load implantation is often needed. But the special non-immediate load implant for the aged is lacking clinically. Therefore, the research and development of the non-immediate planting body for the old has important clinical significance and social value.

Clinically, after dentition is missing or defective due to various reasons, alveolar ridges gradually collapse due to lack of physiological stimulation, and bone mass insufficiency may be caused. The alveolar bone height of a large number of patients with senile tooth loss is still acceptable clinically, but the bone width is seriously insufficient, immediate implantation is often completed without bone implantation, an implant is implanted into the jaw side/tongue side, a gap is reserved between the implant and the lip/buccal side, bone powder can be implanted, but the exposed screw thread on the jaw side/tongue side of the implant is difficult to implant the bone. Based on this, this application designs a non-instant planting body of old age.
